State.
Further, the downlight is using the light emitting diode of three kinds of colors, and the anode of the light emitting diode is by limit
Leakage resistance and driving circuit are with controlling three control ports of chip to be connected, the minus earth of light emitting diode.
A kind of control method of washing machine polychrome downlight control device, comprises the following steps：
（1）The current operational process or working condition of detection washing machine in real time, the working condition include starting shooting, running, suspending, washing
Clothing terminates, shuts down, fault alarm；
（2）According to the operational process process or working condition of detection, the color mode under current operational process or state is chosen；
（3）According to the color mode of selection, which is divided into the RGB three primary colours parameters for matching needs, which passes through control
The PWM module of built-in chip type sends the control signal of different duty；
（4）Control circuit is overturn by logic, and output duty cycle signal, three primary colours lamp source is combined according to different duty cycles
Conducting, shows different combined colors, realizes the multicolor displaying of downlight.
As shown from the above technical solution, a kind of washing machine polychrome downlight control device of the present invention and control method,
The polychrome downlight of proposition is in addition to illuminating effect, available for different working conditions is clearly indicated, helps to visualize washing machine
Operation control, increases user's property easy to use, promotes user experience.
Description of the drawings
Fig. 1 is the circuit diagram of the present invention；
Fig. 2 is the control flow chart of the present invention.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of washing machine polychrome downlight control device, including the polychrome being mounted in the door body plastic ring of washing machine
Downlight and control circuit, the downlight use the LED diodes of three kinds of colors, and control circuit includes current-limiting resistance and driving circuit,
The current-limiting resistance includes resistance R614, resistance R616, resistance R618, and control circuit includes triode Q601, Q602, Q603, and three
The anode of the LED diodes of kind of color respectively by resistance R614, resistance R616, resistance R618 and triode Q601, Q602,
The collector connection of Q603, the emitter of triode Q601, Q602, Q603 are connected with power supply, and resistance is separately energized in base stage
R608, R609, R610 are connected with control chip MCU.
After washing machine is powered, main control chip can detect the working condition residing for washing machine in real time, then according to operation
Process and state persistently read the actual demand that downlight is lighted, the RGB three primary colours parameters of configurations match demand, by software control
After logical process processed, by the actual control signal of three road PWM control ports outputs, signal protects circuit about by external downlight
Shu Hou lights downlight by the color of working condition demand.Three tunnel different duties are sent by the PWM module of software control chip
Control signal, driving circuit carry out logic overturning, and the constant signal of three tunnel duty cycles of output, then this three tunnel is with certain duty
The signal of ratio is applied to three primary colours lamp source by current-limiting resistance and terminal, and last three primary colours lamp source is carried out according to different duty cycles
Combination conducting, so as to show different combined colors.
Fig. 2 is control flow chart of the present invention, as shown in Fig. 2, specific as follows
Step1：The course of work or state that monitoring washing machine is presently in real time, can be right according to the actual conditions of washing machine
The whole work process or state of washing machine are divided, for example are divided into start, operation, pause, laundry knot by washing machine state
The states such as beam, shutdown, fault alarm；
Step2：According to the process or state of the Step1 operations detected, the actual demand that downlight is lighted persistently is read, and is chosen
Color mode under currently running process or state；
Step3：According to the color mode that previous step is chosen, by the RGB three primary colours parameters that the color separation is matching demand, red_
Value, green_value and blue_value, the excursion of this 3 parameter values is [0,255]；
Step4：PWM module processing：The PWM module of control built-in chip type can generate 3 tunnel duty cycles and distinguish adjustable arteries and veins
Pulse modulated waveform first configures the registers such as the clock source, output mode, cycle interruption of the module, then sets PWM
Duty cycle, tri- parameters of R, G, B（Red_value, green_value and blue_value）It is respectively written into accounting for for 3 PWM
Sky is so the signal for outputing 3 tunnel different duties than the low level and a high position of register.
Step5：The signal of this 3 tunnel different duty is after external downlight protects circuit constraint, you can by working condition
The color of demand lights downlight.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the technical side of the present invention
The various modifications and improvement that case is made should all be fallen into the protection domain that claims of the present invention determines.
